I have a virtualized Office 2003 package (merged isolation mode) with few extra bits (reference manager, some add-ins etc) and it works absolutely fine apart from one thing. When clicking option "Edit in Microsoft Word (Excel, PP)" on any of Intranet portal document, message "edit document requires a windows sharepoint services-compatible application" appears. PCs are running on Windows XP, mostly SP2 and SP3.
I guess problem is in missing registry keys on client PC sand Owssupp.dll registration as IE is installed on the machines while Office with Sharepoint Services component is virtual. One solution would be adding IE to virtual app package but I'd rather avoid creating a gigabyte packages, plus that would lead to even more problems with integrating virtualized IE and Windows.
I went through HKEY_LOCAL_MACHINE.txt created when capturing Office installation and changed keys that looked responsible for this to isolation_writecopy mode, but still no joy, google doesn't give me any working solution either.
Has anyone resolved this problem successfully? I don't really want to spend a week diging through all registry, specially that some class IDs for objects could be different on all host PCs, so any hints would be appreciated.
